Romaji from AnimeLyricsRasen
Spiralatashi no dokoka de nanika ga kieuse
sabitsuita ikari wo tebanasou to shiteru
Somewhere deep inside of me something is disappearingatashi wa tori ni nari zattou wo tonde yuku
This anger I've had for so long, I am about to let it go
mayoi wa hane ni nari subete wo furikitte yuku
I will transform into a bird and fly through all the turmoil
My doubts will become my wings and I will shake them all off
